19) how might specialization encourage trade? a) one nation will sell its specialty to others only if they don't compete. b) nations stop using products from other nations to support their own economies. c) nations agree to work together as a team to make it easier for them to manufacture expensive items. d) one nation will focus resources on its specialty, forcing it to buy other products from other nations.

The correct answer is D.

Each nation will specialize in producing goods or services for which it has a comparative advantage, while other products will be imported from abroad. Each country would do the same and therefore an intense international trade will be established so that countries can purchase a variety of products and not only the ones that each manufacures.

A country A has a comparative advantage in producing good X (with respect of another good Y) if the production process of X is retatively more efficient than in other countries. This means that the opportunity cost of producing X, measured in units of good Y, is lower.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
